Enterprise's Pioneer Processing Plant Begins Commercial Operations.

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) today announced that its state-of-the-art Pioneer natural gas processing plant in Sublette County, Wyoming, began commercial operations on February 1, 2008. Production at the facility is currently ramping up and the plant is expected to be processing approximately 525 million cubic feet per day (MMcf/d) of natural gas from the Enterprise-operated Jonah Gas Gathering System and extracting approximately 25,000 barrels per day (BPD) of natural gas liquids (NGLs).

"Pioneer adds another important component to our western natural gas and NGL value chain, which provides customers with much-needed midstream services and an outlet for production in the prolific Greater Green River Basin," said Michael A. Creel, Enterprise president and chief executive officer. "This achievement would not have been possible without the outstanding efforts of our dedicated personnel who overcame severe weather conditions, as well as engineering and operational challenges, in order to bring the facility online in a timely manner."

Located near the Opal Hub in southwestern Wyoming, Pioneer is designed to process up to 750 MMcf/d of natural gas and extract as much as 30,000 BPD of NGLs. Enterprise intends to maintain the operational capability of its silica gel natural gas processing facility, which is adjacent to the Pioneer cryogenic plant, as a back-up to provide producers with additional assurance of the partnership's processing capability at Pioneer. NGLs extracted at the Pioneer facility are transported on the partnership's Mid-America Pipeline (MAPL) and ultimately to Enterprise's NGL fractionators in Hobbs and Mont Belvieu, Texas.
